Loss of a previously possessed ability to carry out motor activities despite intact comprehension and motor function; may be seen in dementia.
Loss or impairment of ability to perform coordinated movements, especially impairment of the ability to use common objects for their intended purposes.
The inability to recall skilled movement, usually as a result of brain damage.
Inability to carry out purposeful movements not due to muscle or sensory impairment.
A condition in which someone is unable to make proper movements.
Inability to produce in sequence the movements necessary to draw shapes and figures or copy words and letters, because of inadequate development of fine motor skills.
Loss or impairment of the ability to make purposeful movements, usually caused by a neurological disorder.
Inability to use or manipulate objects while still being able to name and describe how the object is used.
A loss of the ability to carry out previously learned skills or gestures despite normal muscle power and coordination. Apraxia is caused by brain damage associated with problems such as Alzheimer’s disease, stroke, brain tumor, or head injury. Symptoms can include difficulty using an arm or leg or even making purposeful facial movements on command.
An inability to make skilled movements with accuracy. This is a disorder of the cerebral cortex resulting in the patient’s inability to organize the movements rather than clumsiness due to weakness, sensory loss, or disease of the cerebellum. It is most often caused by disease of the parietal lobes of the brain and sometimes by disease of the frontal lobes.
Apraxia, or dyspraxia, is the loss of ability to make accurate skilled movements. The cause is a disorder of the cerebral cortex of the brain: the patient is unable to coordinate his or her movements. Apraxia differs from clumsiness resulting from muscular weakness, loss of sensation or disease in the cerebellum. The condition is usually a consequence of disease in the brain’s parietal lobes, though frontallobe disease may cause it. A person with gait apraxia has normal power in the legs and no abnormal signs suggesting cerebellar disease, but cannot perform the normal act of walking because of malfunction in the cerebrum.
Inability to perform purposive movements although there is no sensory or motor impairment.
A condition marked by the limitation in executing deliberate movements, while retaining the capacity for sensation and absence of paralysis.
Apraxia refers to the inability to execute purposeful movements, despite having normal muscle strength and coordination. It occurs when the nerve pathways in the cerebrum, the largest part of the brain responsible for translating the idea of a movement into an actual action, are damaged. Individuals with apraxia typically possess the understanding of what they intend to do but struggle to recall the sequence of actions required to carry out the movement. Damage to the cerebrum can result from factors such as head injuries, infections, strokes (caused by interruptions in the brain’s blood supply), or brain tumors.
Apraxia manifests in various forms, with each form associated with damage in different regions of the brain. Ideomotor apraxia refers to the inability to execute a specific movement upon receiving a verbal command, while still being capable of performing the same movement unconsciously at other times. In sensory apraxia, individuals may struggle to utilize objects due to a loss of the ability to recognize their intended purpose.
Agraphia, which refers to difficulties in writing, and aphasia, characterized by severe difficulties in expressing language, are considered distinct forms of apraxia with their unique manifestations and challenges.
The recovery process for apraxia varies greatly and is contingent upon the underlying cause. In cases of apraxia, where skills are lost, it may be necessary to undergo a process of relearning those skills.
